Justin Trudeau walked up the tree-lined path to Rideau Hall to a hero's welcome from a huge crowd of people, flanked by his wife Sophie Gregoire, their children and his top Liberal lieutenants. Spectators represented a mosaic of Canadian culture, from recently-landed Filipino immigrants to retired public servants.

As Canada's 23rd prime minister, Trudeau defeated Conservative Stephen Harper in a landslide victory on Oct. 19, who governed Canada for nearly a decade. While credited by supporters for steering Canada through the global financial crisis, Harper was also criticized for undermining environmental laws in the pursuit of oil and gas projects.

Trudeau also announced his 30 cabinet ministers, 15 of whom are women.
